My first tip is definitely do not picture your audience in their underwear. Trust me, it never works.
When we get nervous and anxious before a presentation – whether we’re presenting to one person, three people, our boss, our colleagues, or to a room full of 400 strangers – our physiology takes over. It’s really common to get a tight chest and sweaty palms and knocky knees and butterflies in our stomach.
The best way to tackle it is through your breathing because if you can get in control of your physiology, then you can get in control of your body. If you can control your breathing, you can control your body.
A really good way to do that is through breathing exercises. One that I learnt through Feldenkrais which is a body movement technique. So it’s breathe in for 1,2 3, 4 (seconds). Hold for 2 (seconds) and then out for 1,2 3, 4 (seconds). Breathing has so many benefits. It calms you down, it gives you a central point of focus and it helps distract you from your worrisome thoughts.
Breath through your nerves. I promise it’s one of the best strategies to deal with stage nerves.
